The purpose of this paper is to obtain a set of genetic information, capable of offering important support to adequate planning and carrying out of conillon coffee (Coffea canephora Pierre) breeding programs. Thus , the following biometric analyses were accomplished: genetic and environmental parameter estimations; phenotypic, genotypical and environmental correlations; repeatability of the character grain production; discriminating analysis for genotype classification; and analysis of genetic divergence, in which different multivariated methods were used. Information was used related to a set of traits, some of which submitted to only one repetition, obtained from an experiment arranged in randomized block design, with 80 treatments and 4 repetitions, which made possible to obtain the varieties EMCAPA 8111, EMCAPA 8121 and EMCAPA 8131.These were the first clonal varieties of the species, obtained and recommended in Brazil.The high estimates of the genotypical discriminating coefficient (H2) to all characters considered in this stage, as well as, the tendency of the values obtained in the genotypical correlation estimates, to overcome in magnitude, those verified in the phenotypical correlation, point out the predominance of the components of genetic variation in relation to those of enviromental variation. The selections of individual for the character grain production, based on 4 crops, presented an accuracy, estimated by the determination coefficient (R2), varying from 65.32 to 81.59%, depending on the estimation method used. The original classification of genotypes presents great agreement with that obtained through the discriminating analysis, with an apparent error ratio of only 6.25%. The genotypes ES 22, ES 35 and ES 92, belonging, respectively, to the varieties EMCAPA 8111, EMCAPA 8121 and EMCAPA 8131, showed to be the most divergent in the group,the first two being the most adequate for breeding programs to obtain hetereotic hybrids, also considering, the genetic divergence and their individual performance. Expressive genetic dissimilarity among the genotypic components of each clonal variety studied was observed, indicating their adequate composition, with clones distributed in various dissimilar groups. The implications of this and other information are dicussed related to the establishment of efficient breeding programs for the species.
